The decrease of Arctic sea ice volume is investigated using a dynamic‐thermodynamic sea ice model. The model was forced with NCEP/NCAR reanalysis winds and surface air temperatures in a hindcast simulation of the period – Following the summer melt period, according to the US National Snow and Ice Data Centre (NSIDC) on 10 September the Arctic sea ice covered million square kilometres, tied with as the second lowest in the satellite ements of ice extent or area however only give a two-dimensional view of the Arctic, whereas volume.

The basis of the classification algorithm, which is developed using a late wintertime Bering Sea ice cover data, is that frequency distributions of ‐μm radiances provide four distinct peaks, representing open water, new ice, young ice, and thick ice with a snow cover. The results are found to be spatially and temporally by:

Sea ice model reanalyses (e.g., Schweiger at al., ) provide useful estimates of thickness and volume.
Satellite records show the minimum Arctic sea ice extents (SIEs) were observed in the Septembers of andbut the spatial distributions of sea ice concentration reduction in these two years were quite different. Atmospheric circulation pattern and the upper-ocean state in summer were investigated to explain the difference.

While the extent of the Arctic and Antarctic sea ice covers has been measured for some time, sea ice thickness values are needed to obtain the mass balance which will offer a much more complete assessment of the state of the global sea ice by: The drifters were deployed in an array designed to resolve four, nested spatial scales of sea-ice deformation, from 10 to km, with the arrays maintaining appropriate shape for strain-rate calculation until mid-June.
